Yeehaw, it's another blog! I'll try and stick to topics relating to WordPress and Automattic, Inc. Of course, nothing here is edited or approved by Automattic or any other entity. These are my views. Your mileage may vary.

I’ve noticed that babies yawn a lot. One theory about contagious yawning is that it was to help synchronize sleep cycles (and is vestigial). Maybe infant yawning is an attempt to get the mother to sleep when the infant sleeps (a good idea, if you’re to get any sleep at all).

Somewhere between ages 4 and 6, children begin to be susceptible to yawning contagion themselves, perhaps signaling that they’re ready to start sleeping when the rest of the tribe sleeps.
